Firefox has always been my favourite browser, and I hope it always stays to be like this. Reason? Because of all the functionality it has, and the fact that it allows expansion of its features thanks to plugins and extensions.

Here’s a simple trick by which you can duplicate an already opened tab in Firefox. I still don’t get its use, but Firefox has this ‘feature’ in it.

Today morning while browsing on Firefox, I found a new trick to quickly open new tabs. May be you would already be knowing about it, but for me it was new and I thought I would also share it with you in case you didn’t know about.

I accidently doubled clicked at the empty area in my tab bar (mostly its full), and suddenly a new tab opened. At first, I thought I must have used to key combination for that. But again when I double clicked in that area, another new tab opened. Till now I’ve using the Ctrl + T key combination to open new tabs, but I guess this new trick will help me open tabs more quickly!

With the release of Firefox 3, a new address bar was introduced which along with your URL history, also drops down URLs from you bookmarks.

This has proved handy for some people, but many dislike it and have their own opinions why it shouldn’t be like this. Here is a small about:config trick that will enable you to disable this awesomeness.

If you are a Firefox user, then you must have noticed that when ever you open an image in Firefox which is larger in resolution than your screen area, it automatically gets resized to fit your screen. Firefox, by default, does not provide an option to disable this but you can always do it through Firefox about:config configuration options.

Firefox is everyone’s favourite browser! I love the tabbing feature. I can open as many tabs as I want. The only thing I don’t like about Firefox is its memory hogging habit. My Firefox eats about 70MB of RAM with only two or three tabs opened. Sick, isn’t it?

Would you like it, if your Firefox memory usage becomes to only 100-200K? No, I’m certainly not joking! It’s seems like a miracle, but I have no idea how Firefox Ultimate Optimizer drastically reduces the browser’s craving for memory and CPU. This little app doesn’t have any configuration options and sits in your system tray all the time.
